Patented Dec. 25, 1934 mansrnnnma mmrns Joel F. Sheppard, Dover, N. E,aaaignor to 11.1. M. Kidder Press Co. Inc.) Dover, N. 11., a

corporation of Delaware A p ication December 13, 1932, Serial Nam-1,002a (01. 242-55) This invention relates to a functionally and structurallyimproved transferring apparatus by such apparatus.

It is an object of the invention to provide an apparatus of this naturein which, for example, a delivery roll is placed in association with themachine and the material is slitted and distributed to one or morereceiving spools or shafts:

By means of the present invention it willbe found that the coils ofreceived material are distributed in such manner that they are capableof separation from each other without danger of mutilation, and that,moreover, where readily desired, the web strips comprising the separatematerial ribs are of uniform width.

A further object is that of providing an apparatus of this nature whichwill embody relatively few parts, each individually simple and rugged inconstruction, and capable of assemblage to furnish a-machine operatingover long periods of time with minimum of manual attention and freedomfrom difliculties.

Referring to the annexed drawings, there has been illustrated twopractical embodiments of the invention, and in these drawings Figure 1is a side view of one form I machine;

Figure 2 is an end view thereof, and

of the Figure 3 shows a slightly different form of apparatus.

While the present machine is primarily intended for use in connectionwith the slitting and transfer of material webs, such as paper,transparent cellulose, cloth, etc., it will be appreciated by thoseskilled in the art that the teachings of the invention might readily beembo a transferring and printing machine.

died in of disks 9 for cooperation with shearing cutters 10. Thestandards 6 may also support guide rolls 11, 12 and 12', and if aplurality of receiving rolls are employed, additional guide rolls 13 mayalso be mounted by the standards. 5 mounts or provides track portions 15an and 14 The base d16,to

each side of the standards 6. Mounted upon the former is a carriage 17supporting a mill roll shaft 18. It is, of course, obvious that thiscarriage might have any desired height with respect to an adjacentsupporting surfaceso that a minimumeffort will be required to bring themill roll to position thereon.

Mounted upon the track portion 16 is a second carriage 19. In theembodiment under consideration, two receiving rolls 20 and 21 aremounted by this carriage, and synchronous movement of these rolls isassured by, for example, a gear train 22. It is obvious, however, thatif desired, the carriage 19 might. merely mount a single receiving roll,in which case the apparatus could be simplified accordingly. In any caseit is preferred that the web or strips of material fed through themachine be moved incident to the fact that they are secured to one ormore receiving rolls which may in turn be power driven by a motor 23.

Referring to Figure 3, it will be noted that the base 5 provides ormounts a standard 25 which is fixed. This standard mounts one .or morereceiving rolls, as I heretofore described. However, in-this form of theinvention, the central portion of the base mounts or provides trackportions 26 upon which is movably mounted a carriage 27 carrying partscorresponding to those which are mounted by the standard 6 in Figures 1and 2. In addition, one end of the base mounts or provides trackportions28 upon which there is movably mounted acarriage 24 which supports themill roll shaft 18, as heretofore described.

Referring again to the first figures, it will be understood that a millroll is positioned upon the carriage 17 and that the web is threadedaround the guide roller 11, then over and around the roll '7, andthereupon under and around the roll 12. If a single receiving roll isemployed, the web merely passes over and around the roll 12" and thenceto the roll 21. If, however, a second receiving roll is utilized,certain portions of the web will be disposed in the manner aforenoted,but others of the same will pass only partially around the roll 12 andwill then transfer to the roll 13 and'over and around the roll 14 andthe roll 20.

If a set-up of apparatus such as has been illustrated in Figure 3 isutilized, the parts are threaded in precisely the same manner asheretofore noted, it being observed, however, that while, as shown inFigures 1 and 2, the carriages 1'7 and 19 are shifted or permitted tomove toward the standard 6, in the structure illustrated in Figure 3,the carriages 24 and 27 may shift with respect to the standard 25. Inboth instances the cutters or other apparatus supported by the standard6 or carriage 2'7 are properly set up and the machine is now ready foroperation.

In both forms of the invention it will be observed that the web ormaterial strips are supported substantially constantly in their travelfrom the material roll to the receiving roll or rolls. In other words,there are substantially no gaps between the supporting surfaces. As aconsequence of this construction, it has been found that any tendency ofthe web or strips to weave is virtually iorestalled. In thestructureshown in Figures 1 to 3, it is obvious that as the motor.

23 beginsto operate, the carriage 17 or 24 as the case may be-due tofrictional drag--will shift to a position at which the last convolutionof the material on the mill roll will be in intimate contact with theguide roll 11 and this will be true throughout the entire operation, anddespite the decreasing diameter of the mill roll, as the material isunwound from the same. Also, incident to the drag of the material thecarriage 19 01' 2'7 will shift to positions at which the receiving rollwill be constantly in intimate contact with the last guide roll. 01.course, it the construction shown in Figures 1 and 2 is employed, thetensioning rolls 12' and 14 will be in contact respectively with rolls21 and 20. It will be appreciated that. regardless of this factor,however, as the receiving roll or rolls build up incident to theincreasing number of material convolutions upon their bodies, thecarriage 19 will be free to shift outwardly without, however, in anysense of the word affecting the fact that there will be no gaps orspaces within which the material web or strips are unsupported.

In the case of apparatus such as shown in Figure 3, the carriage 24 willshift increasingly toward the guide roller 11 as the convolutions oi.the mill roll decrease in number, and likewise the carriage 27 willshift increasingly away from the receiving rolls 20 and 21 as thediameters of these rolls increase. 1

Thus, among others, the several objects of the supporting said operatingmeans to reciprocate with respect to said receiving roll, whereby tosubstantially constantly support the material in its movement from oneroll to the other.

track portions associated with said base and ex tending substantiallyhorizontally, carriages mounted upon said track portions, a deliveryroll mounted by one of said carriages, material manipulating rollsmounted by the other of said carriages, a support fixed with respect tosaid base, a receiving roll carried by said support and a motor coupledto said receiving roll, whereby a web of material extending from saiddelivery roll through said operating rolls to said receiving roll willdraw said carriages towards each other and towards-said receiving rollto maintain said rolls in peripheral contact with the materialsubstangtially constantly supportedrby said several r0 3. A transferringapparatus including a base, track portions forming a part of said base,carriages mounted upon said track portions, material manipulating rollsupon one of said carriages, a support fixed with respect to said base, areceiving roll and a delivery roll, one ofsaid rolls being disposed uponthe second of said carriages and the other of the same being mounted bysaid fixed support, whereby upon said receiving roll being driven, saidcarriages will be drawn towards each other and towards the fixedsupport.
